I'm going to start
First I downloaded the entire game, the one that weighs 7 Gb, unzipped it and started playing
playing I found the bug of the flickering screen and I used what Symphony of the Night published for the unofficial bug, grateful I was able to continue playing, until I got to the same problem, the semifinals were repeated.
so what I did is decompress the game again in another folder, the 7 Gb one. Since that does not contain the patch that Symphony of the Night published, I copied the ¨Save¨ page and started playing and so you can continue playing. ..
Hope this can help you
